4. Genetically, pure white dogs, when crossed to brown dogs produce an all white F1. Data on F2 progeny reveals: 136 white; 41 black; and 13 brown. This coat color trait in dogs is said to be exhibiting dominant epistasis following a 12: 3: 1 expected ratio. Test this hypothesis by chi square.

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
